5. Filter Systems
It is recommended that bacteria filters are fitted in the
fresh gas supply and on the patient side of the exhalation
block.
The filters reduce the possibility of infection to the patient
and contamination of the ventilator from secretions or
fluids in the breathing circuits that could accidentally
enter the ventilators gas ports.
It is recommended that a silencer be fitted on the exhaust
side of the exhalation block, this helps to reduce the
noise level of the system.
The SLE2000 HFO+ can be used without bacterial filters in place, but the user must take extra
care in not allowing secretions or fluids to enter the ventilators gas ports.

5.2.1 Precautions when using bacterial filter N2587
The user should be aware that any occlusion of the filter increases the resistance to airflow,
resulting in increased or erratic airway pressures. Airway pressures should be monitored
during use and the filter changed if found to be contaminated in any way. When using
humidification the filter should be checked regularly for signs of water build up which could
cause occlusion.
